Why does a car traveling at constant speed can accelerate while a car at constant velocity connot?
The question is inherantly flawed. A car traveling at a constant speed cannot accelerate, if it could it's speed would not be constant. "Constant speed" means that speed is not increasing or decreasing but remain consistent over time. For example, if you cover 10 feet during each second, your speed is constant. "Constant velocity" implies constant speed, but it has an additional constraint: you can't change your direction. If you travel constantly at 10 feet per second in a straight line, then your speed is constant and your velocity is constant. But if you travel constantly at 10 feet per second in a wiggly line (or a circle, or anything not straight), then your speed is constant but your velocity is NOT constant. If you travel at a constant speed but change direction, velocity is changed. Or if you travel in the same direction but change the speed, velocity is changed. Average speed is is easier: distance/time So, your question should read: Why can a car traveling at an average speed accelerate, but a car traveling at constant speed cannot? Or Why am I asking the wrong questions?
What happens when unbalenced force acts on an object?
When an unbalanced force acts on an object, it causes the object to accelerate in the direction of the force. This acceleration could result in the object moving faster, slowing down, or changing direction. The object will continue to accelerate as long as the unbalanced force is applied.
If an unbalanced force acts on an object what could change?
If an unbalanced force acts on an object, it could cause the object to accelerate in the direction of the force, change its speed or direction of motion, or cause the object's shape to deform if the force is strong enough.
If an object has zero acceleration what two things could be true about its velocity?
The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.
What path might an object take that involves changing its velocity?
An object might follow a curved path or change direction to alter its velocity. This could happen due to external forces like gravity, friction, or applied forces. The object could accelerate, decelerate, or change direction to adjust its velocity.

Can a body have a constant velocity and still be accelerating?
No. Acceleration is defined as the rate of change of velocity. If velocity is constant, then its rate of change is zero. --------------------------------------------------------------------------- Another contributor obfuscated: If we were to get really picky with our vectors we could say that an object could have constant velocity in the x-y plane and still accelerate in the z-axis. Also a system of objects could have a net-velocity in 3-D space and still have a radial acceleration. A solar system traveling through space at constant velocity will have a radial acceleration, for each component part of the system, around the gravitational center of mass of the system.
What happens when unbalenced force acts on an object?
When an unbalanced force acts on an object, it causes the object to accelerate in the direction of the force. This acceleration could result in the object moving faster, slowing down, or changing direction. The object will continue to accelerate as long as the unbalanced force is applied.
If the net force on an object is zero then the object is?
Not accelerating. It could be stationary or moving at a constant speed.
What is single number without a variable?
Constant, perhaps scalar constant. Since you could have a constant vector or other object, as well.
If an unbalanced force acts on an object what could change?
If an unbalanced force acts on an object, it could cause the object to accelerate in the direction of the force, change its speed or direction of motion, or cause the object's shape to deform if the force is strong enough.
Why must a force be exerted in an object ti change its velocity?
We know that that is the way our Universe works; WHY the Universe was designed that way, or why it happens to be that way, is normally not known.In this case, with a different law for velocity, lots of the physics we know would be drastically different - for example, conservation of energy, conservation of momentum, and conservation of angular momentum could all be violated.
The net force of an object is zero can you conclude that the object is at rest?
You can't. The net force simply means that the acceleration is zero. It could be at rest, or the object could be moving at a constant velocity.
How would you find the mass of an object if there were no gravitational force?
Mass is defined as resistance to acceleration, so one could measure how much force is needed to accelerate the object.
If an object has zero acceleration what two things could be true about its velocity?

What Two dimensional motion is not always project on mission and two dimensional motion that is not projectile motion blank is not accelerating the object?
Two-dimensional motion that is not always projectile motion would be circular motion, where an object moves in a circular path. Two-dimensional motion that is not projectile motion and does not accelerate the object could be uniform circular motion, where the speed is constant but the direction changes.
